DIY Bottle Opener
I recently made this bottle opener on the milling machine from some aluminum bar stock. As you can see from the photos, it has changed a bit since my original CAD sketch, but I've decided to include the drawing anyway.
It's very strong and light. If I were to do it again, I'd probably make it thinner than the current 0.200" thickness, and would reduce the length of the thin extended arm and increase the length of the part before the "hook" to give the user a slightly longer lever arm. Humberto had the idea of having the step in the thin extended arm to allow it to better deform the metal bottle cap (contacting roughly at its center) instead of simply prying it off (contacting at the far edge of the bottle cap as per the CAD sketch). Any opinions on which is better?Two photos and a sketch:
